HKUST-1/ABNO-catalyzed aerobic oxidation of secondary benzyl alcohols at room temperature

Efficient heterogeneous Cu-catalyzed aerobic oxidation of benzyl alcohols was discolsed. The combination of HKUST-1 and ABNO exhibited enhanced catalytic activity compare to the previous HKUST-1/TEMPO system in aerobic oxidation of benzyl alcohols. It was observed that the present catalyst was intrinsically heterogeneous and reusable.     

Aerobic oxidation of secondary alcohols in water with ABNO/tert-butyl nitrite/KPF6 catalytic system

A green and efficient transition-metal free ABNO/tert-butyl nitrite/KPF₆-catalyzed aerobic oxidation of secondary alcohols in water has been achieved. Under the optimal reaction conditions, a number of secondary aliphatic alcohols and secondary benzylic alcohols can be converted to their corresponding ketones in excellent yields (up to 99%).     

Direct synthesis of imines by 9-azabicyclo-[3,3,1]nonan-N-oxyl/KOH-catalyzed aerobic oxidative coupling of alcohols and amines

A simple and efficient method for preparation of imines by the oxidative coupling of alcohols and amines using ABNO/KOH as the catalysts, and air as the economic and green oxidant was developed.
